摘　　要：高陡岩质边坡生态绿化修复难度较大,常因喷播基层脱落、缺水、养分缺失等因素,造成修复治理效果不理想,甚至出现岩壁裸露、治理失败等情形。文章采用纵向生态长袋法施工工艺,对北京某高陡直立边坡进行修复治理,复绿效果达到90%以上,取得较好的短期工程治理效果。但从长远来看,如何做到治理效果长期保持,实现生态系统的重建,还存在治理后责任主体缺失、养护难度大、材料耐久性差、结构安全稳定性差和植被生根难度大影响生态系统重建等风险和不足。建议增强主管部门巡视,加强养护期后保护,及时处置老化出现质量缺陷的防护结构,增强后期水分、养分持续供给,保证治理效果达到长期有效保持,实现工程修复治理的目的。The ecological restoration of high and steep rocky slopes is often challenging,frequently resulting in less-than-ideal outcomes due to factors such as the detachment of the spray-applied base layer,water scarcity,and nutrient deficiencies,which often lead to exposed rock faces and even failure of restoration efforts.In this paper,through a restoration and treatment project in Beijing,the vertical ecological long bag construction technology is adopted to restore and treat a high steep vertical slope(greater than 60°degrees).The results show that the greening effect reaches more than 90%,and short-term engineering treatment effect is quite satisfactory.However,long-term maintenance of the governance effect and ecosystem reconstruction still face risks and deficiencies such as lack of responsible subjects after governance,difficulty in conservation,poor durability of materials,poor structural safety and stability,and difficulty in rooting of vegetation affecting the reconstruction of the ecosystem.Suggestions have been put forward on effective site-inspection by the competent authorities,strengthened post-maintenance protection,timely disposal of the defective protective structures caused by aging,and continued supply of water and nutrients in the later period.In this way,it is hoped that the long-term treatment effect can be effectively maintained and the purpose of the restoration and treatment project can be fulfilled.
